漳州市森林生态系统固碳释氧服务功能评估

Evaluation of the Service Function of Carbon Fixation and Oxygen Release of Forest Ecosystem in Zhangzhou City

依据2009—2011年漳州市森林资源清查数据,将漳州市森林分为6种类型:经济林、竹林、阔叶林、灌木林、杉类、松类,分析各类树种的面积和蓄积量,根据城市森林固碳释氧功能评估方法,分别计算各类型固碳释氧功能的经济价值,量化森林生态系统固碳释氧服务功能。结果表明:经济林固碳释氧量最多;年固碳和释氧总价值排序均为:经济林>竹林>阔叶林>灌木林>杉类>松类;单位面积固碳价值和单位面积释氧价值最高为竹林,是排名次之经济林的2.41倍,建议适当增加竹林种植。

Based on the forest resources inventory data of Zhangzhou from the year 2009 to 2011 , the thesis divides the forest in Zhangzhou into the following six types：economic forest,bamboo forest,broad-leaved forest,shrubwood,cunninghamia lanceolata forest and pine forest ,and it also analyzes the area and forest stock volume of various species .According to the evaluation method of carbon fixation and oxygen release functions for urban forest ,the thesis calculates the economic value of various kinds of carbon fixation and oxygen release functions respectively and quantifies the service functions of the forest ecosystem carbon fixation and oxygen release .It aims to provide the reference for improving the public awareness of urban forest .The result is as followed：the economic forest relea-ses oxygen most;the total value order of carbon sequestration and releasing oxygen is economic forest ,bamboo forest ,broad-leaved forest,shrubwood ,cunninghamia lanceolata forest and pine forest;the highest value of carbon sequestration and releasing oxygen in per unit area is bamboo forest ,2.41 times of economic forest .Suggest appropriate increase of bamboo plant .
